Description
Sinopec L-TSA/LF Long Service Life Turbine Oil is a line of products formulated with high-quality hydrogenated base oils and selective additives. Excellent oxidation stability properties, which reduce sludge and deposit formation, enable this product to be used as a long service life steam/gas turbine oil. Available in ISO viscosity grades 32, 46, and 68.
Applications:
Sinopec L-TSA/LF Long Service Life Turbine Oil is suitable for use in:
- Large supercritical-steam turbines used in power generation.
- Heavy-duty gas turbines.
- Large to moderate marine turbines.
- Industrial steam, gas, and water turbines.
- Combined cycle turbines.
Features and Benefits:
- Perfect oxidation stability inhibiting formation of sludge, ensuring smooth operation and extending oil service life.
- Excellent water separation properties ensure that any water contamination can be easily separated from the oil, protecting equipment against rusting and corrosion and extending oil life.
- Good air release properties protect against air entrainment, ensure optimum oil film thickness and protect equipment components from cavitation.
- Good antifoaming properties avoid the build-up of foam and reduce oil leakage from the system.
- Excellent anti-rust and corrosion prevention properties protect equipment from rusting and corrosion, and extend equipment life.
